I did answer a survey, BUT the calls started coming months before the survey. I called them back and left a message that this would be my one and only request for them to stop calling me, and if they persisted I was going to report them for harassment.
They have called several times, but never left a message. When unanswered they said they were from Alliance health about a recent survey my husband had filled out. My husband DOES NOT fill out surveys so it's obviously a telemarketing scam.
Caller answered: Jensen Medical, but I GOOGLED and it came up with Alliance Health 469-237-3029. In reference to requesting some medical study. At the end of the call, the agent states that they have no medical center locations that service my area.
